Abstract

A system providing methodology for the restoration of original media quality in messaging environments is described. In one embodiment, for example, deployed in a messaging system, a method of the present invention is described for restoring media items to original quality, the method comprises steps of: upon receipt of a message containing an original media item that is new, storing the original media item in a repository; generating an identifier for identifying the original media item stored in the repository; replacing the original media item in the message with a substitute copy that includes the identifier; and upon future encounter of a particular media item having the identifier, restoring the particular media item to original quality using the identifier.

Claims

1. In a messaging system, a method for restoring media items to an original quality, the method comprising:

upon receipt of a message containing a media item having original resolution quality by a switching center, storing the media item having original resolution quality in a repository by a server;

generating an identifier for identifying the media item having original resolution quality stored in the repository by the server;

embedding the identifier in the media item having original resolution quality stored in the repository by the server;

replacing the media item in the received message with a copy of the identifier- embedded media item having original resolution quality stored in the repository by the switching center; and

upon future encounter by the switching center of a message sent by a source node to a destination node, wherein the source node is different from the destination node, the message containing an identifier-embedded media item no longer having original resolution quality, substituting, by the switching center, the identifier-embedded media item no longer having original resolution quality in the encountered message with a copy of the identifier-embedded media item having original resolution quality stored in the repository using said identifier.

2. The method of claim 1, wherein said media item having original resolution quality comprises a component in user-composed messages.

3. The method of claim 1, wherein said messaging system comprises Multimedia Messaging Service (MMS).

4. The method of claim 1, wherein said replacing includes:

using an available data communications channel that exists for encoding said media item having original resolution quality, in order to encode said identifier.

5. The method of claim 1, wherein said messaging system comprises a message switch-based system.

6. The method of claim 1, wherein said messaging system is able to allow transmission of a given media item in its original resolution quality or decimate the given media item, as required for a given destination.

7. The method of claim 1, wherein the message containing a media item having original resolution quality is received from a mobile terminal.

8. The method of claim 7, wherein the mobile terminal communicates via a multimedia messaging protocol.

9. The method of claim 1, wherein said identifier comprises an object reference identifier.

10. The method of claim 9, wherein said object reference identifier is capable of being embedded in the media item having original resolution quality.

11. The method of claim 10, wherein the object reference identifier is embedded in a header of the media item having original resolution quality.

12. The method of claim 11, wherein said media item having original resolution quality comprises a JPEG image, and wherein the object reference identifier is embedded in a header for the JPEG image.

13. The method of claim 1, wherein the identifier is embedded in the media item having original resolution quality as a binary text string.

14. The method of claim 13, wherein the binary text string contains sufficient information to allow retrieval of a copy of the media item having original resolution quality stored in the repository.

15. The method of claim 1, wherein the identifier employed for the media item having original resolution quality depends on the media item having original resolution quality type.

16. The method of claim 1, wherein said substituting includes:

scanning incoming media items for any preexisting identifiers.

17. The method of claim 16, further comprising:

if an incoming media item does not have a preexisting identifier, assigning a new identifier for that incoming media item.

18. The method of claim 1, further comprising:

removing from the repository any media item that is stale.

19. The method of claim 18, wherein said removing includes applying an aging mechanism to determine media items that are stale.

20. The method of claim 1, wherein the identifier is embedded in a digital watermark employed for the media item having original resolution quality.

21. The method of claim 1, wherein said media item having original resolution quality comprises an image, and wherein the identifier is embedded in a digital watermark for the image.

22. The method of claim 1, wherein the identifier is embedded in a digital watermark for the media item having original resolution quality, said identifier be embedded as a binary text string.

23. The method of claim 1, wherein steps of the method are performed at a server computer that connects to mobile terminals.

24. The method of claim 1, wherein at least some steps of the method are performed at mobile terminals, for providing distributed processing.

25. The method of claim 1, wherein said message is transmitted via the Internet from a client device to a server.

26. The method of claim 1, wherein the identifier-embedded media item is a reduced size image smaller than the media item having original resolution quality.

27. A computer-readable medium having processor-executable instructions for performing the method of claim 1.

28. A memory storing downloadable set of processor-executable instructions for performing the method of claim 1.

29. A system for restoring media items to original quality, the system comprising:

a messaging system in a network capable of transmitting multimedia messages;

a repository for storing media items having original resolution quality upon receipt of a message containing a media item having original resolution quality;

a module for generating an identifier for identifying the media item having original resolution quality stored in the repository and for embedding the identifier in the media item having original resolution quality stored in the repository;

a module for replacing the media item having original resolution quality in the message with a copy of the identifier-embedded media item having original resolution quality stored in the repository; and

a module for substituting an identifier-embedded media item no longer having original resolution quality in a message sent by a source node to a destination node, wherein the source node is different from the destination node, with a copy of the identifier-embedded media item having original resolution quality stored in the repository using said identifier.

30. The system of claim 29, wherein said media item having original resolution quality comprises a component in user-composed messages.

31. The system of claim 29, wherein said messaging system comprises Multimedia Messaging Service (MMS).

32. The system of claim 29, wherein said module for replacing includes:

module for using an available data communications channel that exists for encoding said media item having original resolution quality, in order to encode said identifier.
